Hello Mauro Carvalho Chehab,
This is a semi-automatic email about new static checker warnings.
The patch 15472faf1259: "[media] cx23885-dvb: use a better approach
to hook set_frontend" from Aug 9, 2013, leads to the following Smatch
complaint:
drivers/media/pci/cx23885/cx23885-dvb.c:790 dvb_register()
error: we previously assumed 'fe0->dvb.frontend' could be null (see
line 784)
drivers/media/pci/cx23885/cx23885-dvb.c
783 &i2c_bus->i2c_adap);
784 if (fe0->dvb.frontend != NULL) {
^^^^^^^^^^^^^^^^^^^^^^^^^
Existing check.
785 dvb_attach(tda18271_attach, fe0->dvb.frontend,
786 0x60, &dev->i2c_bus[1].i2c_adap,
787 &hauppauge_hvr127x_config);
788 }
789 if (dev->board == CX23885_BOARD_HAUPPAUGE_HVR1275)
790 cx23885_set_frontend_hook(port,
fe0->dvb.frontend);
^^^^^^^^^^^^^^^^^
Patch adds dereference.
791 break;
792 case CX23885_BOARD_HAUPPAUGE_HVR1255:
regards,
dan carpenter
